5 Claims.

Our invention relates to improvements in utility beds which are especially adapted for the treatment of geriatric patients in hospitals and like institutions.

We have invented an invalid bed of simple sanitary construction which is equipped to provide for the comfort of patients and facilities for treating and caring for even such invalids as those who are in a helpless condition. Our bed comprises a frame upon which a sheet of canvas or the like can be stretched to support a patient and can be removed readily for laundering and sterilizing. On April 12, 1949, we filed an application for patent as Serial No. 86,944, now abandoned, in which our invention as it had been developed up to that time is'described and claimed. This bed has gone into successful use. Since that time we have made the improvements described herein, for which we desire patent protection.

Referring to the drawings:

Fig. 1 is a side elevation and Fig. 2 an end view of a bed which is made according to and embodies the aforesaid improvements.

Fig. 3 is a perspective view of some of the parts shown in the preceding figures drawn on a larger scale. The view in this figure is taken on the line 3-3 of Fig. 1.

Figs. 4 and 5 are similar perspective views of other parts which are shown in Figs. 1 and 2. The views in both of these figures are taken from the line 5-5 of Fig. 1 and show the same parts in different relative positions.

A detail of construction is shown in Fig. 6, this being a plan View taken on the line 66 of Fig. 2.

The frame of the bed comprises vertical posts I0, interconnected at their upper ends by longitudinal members I I, I2, and transverse members I3, l4. They are also interconnected intermediate their lengths by longitudinal members I5,

I6 and transverse members ll, [8 located above the numbers I5, I6. These parts are preferably of square hollow metallic tubing, welded together as shown, but the longitudinal members I I, I2, I5 and It may be detachably connected to the posts. A fiat metal transverse bar I9 is welded to the posts which are at the end of the frame, which we will call the head. This bar is located near the lower end of the posts.

designates a longitudinal member rotatably mounted in the posts I0, II! at what we call the front of the bed. It is located above the member I5 in horizontal alinement with the members I I,

I8. Channel brackets 2| are welded to the ends of the member 20, in which are rectangular openings 22. 23 designates levers welded to the brack- 2 ets and projecting at right angles from the member 29. Pintles 241 project from the member 20 through these brackets. The pintles pass through perforations in the posts Ill, whereby the member 28 is pivotally supported.

At the side of the member 20 from which the levers 23 project, are a plurality of spaced studs, designated by S.

It is to be understood that a similar longitudinal member is rotatably supported on the posts I 0 at the rear of the bed, together with part like those which are designated by the reference numerals 2 l24. I

According to our invention, a sheet of canvas or the like, designated by C, having grommets along its edges, is placed over the frame thus described, and is attached thereto by passing the grommets over the studs on the member 20, studs on the bar similar to 20 at the rear of the bed, and similar studs on the transverse members I'I, I8. This is done when the levers 23 are in the positions shown at the right-hand side of Fig. 2 and in Fig. 4. A hook pivoted on the outside of a post I 0 passes through the opening 22 in the bracket 2I and. holds the parts in the positions shown in Fig. 4. Then, when the levers 23 are turned to rotate the member 20 180 degrees, the studs will be moved to the position shown in Figs. 1 and 5, and the canvas will be stretched thereby.

A hook 25A pivoted on the inside of the post II] is used to hold the member 20 with the studs 5 in inverted position (see Fig. 5).

designates one of a pair of side brackets, each of which comprises two vertical posts 3|, 32, the upper ends of which are connected by a horizontal arm rest 33 and by an obliquely disposed bar 34. The bars 32, 33, 34 are provided with studs S for supporting strips of canvas or the like to form a seat for a patient and a table. Flat strips 35, 36 extend downwardly from the posts 3|, 32 to the longitudinal bar l5, to which they are hinged, as shown at 31 in Fig. 3. Both of these strips are offset as shown at A in Fig. 3 to clear the longi tudinal member 20.

The post 32 is spaced longitudinally from the adjacent post ill of the frame. 38 is'an extension projecting from the post 32 to span this space.

, 39 is a hook pivoted to the extension. When the the position under the bed in which it is shown at 30A in Figs. 2 and 6. The hook 39 may then engage the crossbar l9 near one of the notches therein (Fig. 6).

A pair of doors 40 is provided at each end of the bed. These are pivoted in brackets 4| welded to the posts 10. When closed, the adjacent edges of each pair are fastened together by a keylock at 42.

A pair of brackets 43, 44 are welded to each door near its pivoted edge. When the doors are closed the bracket 43 is positioned over the hook 25A to prevent its removal from the bracket 2 i. The bracket 44 will then be over the hook 39 if the latter is in the space. between the post it and the strap 19A.

One or more pairs of self-locking rollers 50 are provided on the longitudinal bars I I, I2, between which a strap for lifting a patient may be passed.

Various modifications in construction, mode of operation, method and use of an invention may and do occur to others, especially after benefiting from knowledge of such a disclosure as that herein presented of the principles involved, but the invention itself is not confined to the present showing.
